LVTTL Output,
asynchronous
Link Fault Indication Output
. LFIx is an output status indicator signal. LFIx is the
logical OR of five internal conditions. LFIx is asserted LOW when any of the
following conditions is true:
Received serial data rate outside expected range
Analog amplitude below expected levels
Transition density lower than expected
Receive channel disabled
ULCx is LOW
Absence of REFCLKx±.

Control Write Enable
. The WREN input writes the values of the DATA[7:0] bus
into the latch specified by the address location on the ADDR[3:0] bus.

Control Addressing Bus
. The ADDR[3:0] bus is the input address bus used to
configure the device. The WREN input writes the values of the DATA[7:0] bus into
the latch specified by the address location on the ADDR[3:0] bus.

Table 9
lists
the configuration latches within the device, and the initialization value of the
latches upon the assertion of RESET.
Table 10
shows how the latches are
mapped in the device.
Control Data Bus
. The DATA[7:0] bus is the input data bus used to configure the
device. The WREN input writes the values of the DATA[7:0] bus into the latch
specified by address location on the ADDR[3:0] bus.

Table 9
lists the configu-
ration latches within the device, and the initialization value of the latches upon the
assertion of RESET.
